2 Claims. 238192) This invention relates to improvements in rail joints.

The primary object of the invention is to provide a rail joint seatformed of duplicate sections which interfit and embrace the base and webportions adjacent the meeting edges of rails.

A further object of this invention is to provide a rail joint seat ofthe above mentioned character having complementary interfitting partsadapted to be locked in position against displacement by means of thejoining bolts as well as the rail spikes.

A further object of this invention is to provide a rail joint seat ofthe above mentioned character which will positively prevent separationof the rails with the resultant accidents to rolling stock of both thepassenger and freight types and which will not be thrown out ofalignment by contraction and expansion of the rails during seasonchanges.

Other objects and advantages of the invention will become apparentduring the course of the following description forming a part of thisspecification and in which:

Figure 1 is a perspective view of the rail seat joint embodying thisinvention, showing the same applied to the meeting edges of a pair ofrailroad rails;

Figure 2 is a horizontal cross-sectional view taken on line 2-2 ofFigure 1, looking in the direction of the arrows, illustrating themanner in which the rail joint seat embraces the web portion of the railend and showing the manner in which the overlapping sections of the railjoint seat members are locked in place by means of bolts;

Figure 3 is a vertical cross-sectional view taken on line 3--3 of Figure1, looking in the direction of the arrows, illustrating the manner inwhich the overlapping extensions engage the web portion of the rail andpartly enclose the base portion thereof; and

Figure 4 is a perspective view of one of the rail joint seat membersillustrating the base engaging member and the web confining portion.

In the drawing, wherein for the purpose of illustrating the inventionand wherein like reference characters will be employed to designate likeparts throughout the same, the reference character 5 will generally beemployed to designate a rail joint seat adapted to join together theends of the abutting rails B and l.

A pair of rail joint seats 5 are employed for effecting the connectionof the two rail ends 6 and I and each rail joint seat comprises a basemember 8 having vertical portions 9 and I0 along the outer edgesthereof. The vertical portion 9 extends inwardly as at l I to conform tothe upper portion of the rail base l2 and extends upwardly as at l3 toembrace the web portion of the rail web l4. The vertically extending webembracing portion l3 terminates directly under the tread of the raildesignated by the reference character I5.

The other vertically extending base portion [0 is inwardly bent as at Hito embrace the upper surface of the rail base l2 and then extendsupwardly as at I! to abut against the web l4. A portion of the verticalbase section III is cutaway as at 18 to receive a complementary cutawayportion l9 formed on the vertical base portion 9. In this manner therail joint seat 5 may interfit so that the inwardly bent portion ll ofthe vertical section 9 may overlap the cut-away portion 18 of thevertical base section Ill.

The construction above described also allows the web embracing portionl3 to overlap the joint between the rail ends 6 and 1 on alternateopposite sides of the rails.

When the rails are placed in abutting position as shown in Figure 1, apair of rail joint seats 5 are arranged so that the web embracingportions I 3 engage opposite sides of the rail web l4 so that bolts 20may be passed through openings 2| formed in the web embracing portion l3and anchored by means of bolts 22.

To further lock the rail joint seats 5 against displacement, cut-outs 23are formed in the vertical base portions 9 and ID for receiving railspikes having heads which are larger than the width of the opening 23 inorder to insure proper anchorage of the base sections 9 and I0.

Since the rail base sections 5 are complementary it will be understoodthat two rail base joints 5 are required to consummate an adequateconnection between the abutting portions of the rail and that variouschanges in the shape, size and arrangement of the sections may beresorted to without departing from the spirit of the invention or thescope of the subjoined claims.

I claim:

1. A rail joint comprising in combination with the meeting ends ofrails, a pair of duplicate chair members, each chair member including abase plate and upstanding side flanges for intimate contact with thebase flanges and webs of the distance equal to the distance or thecut-away side flanges and terminating in vertical planes and with therelatively long and short side flanges abutting at each side of themeeting rail ends at points inwardly oi the abutting ends of the baseplates and rail ends seated'in said chair members with their meetingends in vertical alinement with the abutting ends of the base plates andin a plane intermediate of and parallel with the abutting ends of saidflanges.

2. A rail joint chair, comprising in combination with the meeting endsof rails, a pair of duplicate chair members, each chair member includinga base plate and upstanding side flanges for intimate contact with thebase flanges and webs of the rails, corresponding side flanges of eachchair member terminating in inwardly spaced relation to the abuttingends of the base plates and in vertical planes and the othercorresponding side flanges extending beyond the abutting ends of thebase plates and terminating in vertical planes a distance whereby theflanges at each side of the chair members and the adjacent ends of thebase plates abut with each other when the base plates are assembled withthe point of engage ment between the rail'ends being between the pointsof abutment of the flanges, rail ends seated in said chair members withtheir abutting ends in vertical alinement with the abutting ends of thechair members and anchor means for the rail ends passing through therail ends and overlapped ends of the side flange extensions.

MIKE 'MITIN.
